Cuba is a natural market for U.S. farm products, but U.S. sanctions effectively prevent farmers from selling food to Cuba.

Under U.S. law, Cuba can only buy U.S. food if it pays in cash, in advance — conditions under which no other country is required to operate. As a result, Cuba imports food from other countries that offer credit.

U.S. farmers say they are being hurt by these regulations. Kansas wheat farmer Doug Keesling says “we’ve lost this market” to foreign competitors.
